10 inches bass driver active subwoofer

The mid-sized Kube 10b has a sealed cabinet, 10 inches bass driver and 300 Watts to produce serious extension and control. The latest addition to KEF's powerful range of subwoofers opens up sound’s hidden depths thanks to 300 Watts of Class D power integrated with a 10 inches driver and iBX dynamic bass extension technology.

Hear new dimensions in sound with Kube subwoofers

The Kube 10b effortlessly unleashes explosive power. iBX technology extends the bass depth dynamically and KEF’s unique ability to design, build and integrate the driver in-house takes optimisation to a whole new level. Delivering immersive music and home theatre sound that takes you to the heart of the performance.

Immersiveness

Go deep or go home. KEF’s design and engineering team worked in chorus to develop iBX. This Intelligent Bass Extension algorithm creates an extended depth that unlocks the full potential of the custom driver. Giving you unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet.

Easy configuration

Kube subwoofers offer unmatched set up flexibility. A range of LFE, line and speaker-level inputs, phase selection and DSP controlled EQ settings help you get the best from a Kube. Put it in a convenient place, match it to any main speaker or type of music system and start exploring new depths in the sound.

Integration

KEF is quite possibly the only high-end manufacturer that designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration means we are committed to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.

Meets the Specifications for VW TDI
Size: 1 Quart Pack of 6
I don’t get too excited about motor oil; it just needs to meet the specifications for the application. This oil meets the standards for VW TDI engines (VW 504.00 & 507.00) and several other European turbo diesel engines. While this type of oil is locally available, it is very costly if purchased locally by the quart. There are plenty of other brands like Liqui Moly and Mobile One that offer oils which will meet the specifications, so pick the one you like. After some research, I found there are no great deals in terms of cost, all of the oils that meet the VW 504.00 & 507.00 specifications are going to be on the expensive side. However, Castrol is the brand used by VW, so if that’s important to you, there’s your option. I have used this type of oil for several years and many thousands of miles with zero issues. If you do your own maintenance, you might as well save a little money and buy in bulk. Storage and shelf life of motor oil is not a concern.
